Abstract
The radioactive tracer technique was used to evaluate the liquid and solid (fine and coarse) transport in two industrial semi-autogenous grinding (SAG) mills. The residence time distribution (RTD), along with the mean residence times, was obtained. The residence times for the liquid and fine solid were equivalent, approximately 2min, which implies non-significant segregation in this size class. The residence time for coarse solids was approximately 4min. The RTD was modelled by N perfectly mixed tanks in series, in which the number of equivalent mixers was approximately 2 for liquid and fine solids and approximately 3 for the coarse solids. The coarse particles required additional time to pass the grate discharge restriction, which also favoured the mixing.
